Answer:
15
Step-by-step explanation:
when x = -9, y = 1
Here, we want to get the value of y when x = -9
To find this, we look at the point x= -9 on the x-axis
After getting this, we trace it to the graph
Looking at the graph, the graph crosses the x-axis at exactly this point
What this mean is that the value of y at that point is 1
Hence, for input -9, output is 1
Answer:
x = -1 and y = -4
Step-by-step explanation:
It is given that,
3x - 2y = 5 ----(1)
-2x - 3y = 14 ------(2)
<u>To find the solution of equations</u>
(1) * 2 ⇒
6x - 4y = 10 -----(3)
(2) * 3 ⇒
-6x - 9y = 42 ----(4)
eq(3) + eq(4) ⇒
6x - 4y = 10 -----(3)
<u>-6x - 9y = 42 </u> ----(4)
0 - 13y = 52
y = 52/(-13) = -4
Substitute the value of y in eq(1)
3x - 2y = 5 ----(1)
3x - (2 * -4) = 5
3x +8 = 5
3x = 5 - 8 = -3
x = -3/3 = -1
Therefore x = -1 and y = -4
